Hydrogen And Its Compounds Question 253
Question: In context with the industrial preparation of hydrogen from water gas $ {{(CO+H)}_2} $ which of the following is the correct statement-
Options:
A) $ CO $ and $ H_2 $ are fractionally separated using differences in their densities
B) CO is removed by absorption in aqueous $ Cu_2Cl_2 $ solution
C) $ H_2 $ is removed through occlusion with Pd
D) CO is oxidised to $ CO_2 $ with steam in the presence of a catalyst followed by absorption of $ CO_2 $ in alkali
Show Answer
Answer:
Correct Answer: D
Solution:
[d] On die industrial scale hydrogen is prepared from water gas according to following reaction sequence $ \underbrace{CO+H_2} _{watergas}+\underbraceH_2O _{(steam)}~\xrightarrow{catalyst}CO_2+2H_2 $
$ \xrightarrow[(alkali)]{2NaOH}Na_2CO_3+H_2O $ From the above it is clear that CO is first oxidised to $ CO_2 $ which is then absorbed in $ NaOH. $
